Christ's first preaching seems to have been summarized in one short but crucial sentence, like that of John the Baptist before Him: "Repent ye: for the Kingdom of heaven is at hand" (Matthew 3:2, 4:17). It is not appropriate in a brief study such as this to discuss that most interesting topic, the Kingdom of heaven-what it is and what the various periods of its development are-but these Beatitudes teach us much about those who belong to that Kingdom, and upon whom Christ pronounced its highest forms of benediction.
